Montelukast is a leukotriene receptor antagonist commonly marketed under the brand name Singulair, primarily used for the prevention and chronic treatment of asthma, as well as the relief of symptoms of allergic rhinitis. It works by blocking leukotrienes—chemicals in the body that cause inflammation, bronchoconstriction, and mucus production. Maintaining the pharmaceutical purity of Montelukast is essential to ensure its safety, therapeutic effectiveness, and compliance with regulatory standards. Impurity profiling is crucial to detect and control unwanted by-products that may arise during manufacturing, storage, or degradation. Here are some of its known impurities listed below.
